The separation of Nitrogen from Oxygen using fractional distillation of air is possible because of the difference in their boiling points. Nitrogen has a boiling point of -196°C while oxygen has a boiling point of -183°C. This means that at a certain temperature, oxygen will boil and turn into a gas before nitrogen. By carefully controlling the temperature, we can separate the two gases as they boil at different times. This is known as fractional distillation, which is a process that separates a mixture into its different components based on their boiling points. Therefore, the key factor in separating nitrogen from oxygen is their difference in boiling points, not their density, reactivity, or position in the periodic table.
